all 'whom it ifi-icy concern:

i a subject of the King of italy, and resident. of Lynbrook, in cbs county of Nassau und Stai@ New York, have invented a new snai useful improvement in Solis, oi' ,Vbicii the ioiiowing is :1 specification.

This invention Tristes io an iioprovcmen?. in boiis and bos. for iis object to provide dsvicc for rigidly connecting or associating two or .mors eiemsnis in an ditious, cor.- fv'cnisnt n o economic manncr. Hobbs? objccb is to provide if. i cking;

Another objsc' is to provide c ooitwhich may bc resffiiiy kicked in position and cssiy roiecscd 'when dssired. l

noihei objcci is 'to provide certain improvcmsnts ii.: ibo form, construction and arrangemciii of 'che several parijs whereby tbs above Biomed. and ocbcr objects may fscti'vc'y' bc atsiried.

Fig. 12, rc'prcscnt s side cisvation of the sums, the elements sing shown in section.

The boigt comprissc ihres members denoted by'l, 2 and 3. The clamping mem bcrs '1 and 2 arc similar in construction, nach being provided with s. iat straight innor face 4, c cyiizidrical outer face 5, a bead 6 formed upon one end of the cylindrical face 5 and a head 7 at the opposite end. The bca-d 8 is semi-circular in cross. section and extends beyond the cylindrical ffice 5 to form a shoulder 8, 'the peripheral edge of which is concciitric with the cyiin driczii face 5. The bead 7 is also semi-cir cular in cross section, and is oset from the cyiindrical 'fac-e 5, so hat the peripheral edge is disposed ecccniricaily with respect` to tbc face 5 io .form o silouider 9.

The fiat straight 'face 4 di each member has a recess 10, the purpose of which, will 'bo hereinafter cxpicined.

The central or iociing member 3 is provided with opposteiy disposed fiat, strsight aces and is substan'tisiiy of equal thickbrougbo'ui its length and breadth. @no end. of this member S bas a bead 13 which exi-ends beyond the side walls of the member 'to :form sbouidcrs 111, 15, the contour or which head and shoulders coincides with the peripheral contour of the heads 6, of the members 1, 2, when assembied. A commi iongtudinai slot 16 is formed in the locking; member 3, which slot is arranged to house yioiding tongues 17, 18, Whichare Secured at one end to the member 3 by a rivet 19 or other suitable fastening means. Thesc tongues are disposed on the opposite sides of the member 8, and each tongue is provided with im outwardly projecting featl 20 which is arranged 11o rest in the recess 10 in tho face of the immbers 1, 2 when the members are asso-mbicd in locked position.

To coiineci tbc sisma-nts 21, '22 and 23 in looked engagement, tbc clamping members 1, 2 am placed with their Hat straight faces f1 'togeibcr or appr oximcely so andthe head 7 of both members passcd. into and throu h tbs washer 24, cirooisr soles in the e erna-obs and washer 26 after such holes have been brought into register. The disposition of the members-1, 2 having been accomY plished, the central or locking member 3 is introduced between theV inner flat straight faces 4 of the clamping members 1, 2 and forced therebetween until the shoulders 111-, of the head 13 engage the washer 24, at which point the teats 2O on the yielding tongues 17, 18 will register with and enter the recesses 10 in the faces of the clamping members 1, 2. While the member 3 is passing between the members l, 2q the teats 20 will, of course, slide upon the dat straight faces 4 and cause the free ends of the tongues to lyield inwardly and toward each other. When the teats enter the. recesses,

the tongues will then assume a normal pos1.

tion.

To remove the bolt from the holes in the elements I insert a tool 27, in the form of a flat bar, shown in Idotted outline in Figs. 1 and 2, in the recits 28, between the head 7 of the members 1, 2, until it engages i* the member 3, and by striking the tool a sharp blow with a hammer or other instrument, the teats 20 will be caused to recede or ride' from the recesses 10 at the same time the member 3" moves upwardly. After the teats areY removed from their recesses, the member 3 may be readily removed from between the members l, 2 by the further progress of the tool therebetween. WVhen the member 3 is disposed of, the members 1 and 2 may approach ,each other until the flat straight faces 4 are together, when the heads 7 may then be passed through and from the washer 26, holes 25 in the elements, and washer 24.

In theform shown in Figs. 8 and 9 the locking member 29 is provided with a single yielding tongue 30 andteat 31.

In the form shown in Figs. 10 to 12 inelusive, heads 32, 33 of the clamping members 34:, 35 are each provided with acutaway portion 36, which portions, when the members are assembled, will form a cavity i to allow a hook shaped tool 37, shown in 'departing from the spirit an dotted outline in Figs. 11 and 12, towenter a hole 39 in the central locking member 40, by. which means the member Ll() may be withdrawn from its locked position between the clamping members 34, 35.

It is evident that various changes may be resorted `to in the construction, form and arrangement of the several arts without scope et. my

invention; hence I do not wish to limit myself to the particular embodiment herein shown and describedgbut What l claim isz'- l. 'A lock bolt comprising clamping mem bers having a recess, an intermediate member providedwith laterally movable yielding means arranged to enter said recess for interlocking said members.V

2. A lock bolt comprising clamping mem. bers having a recess, an intermediate mem.- ber provided with a yielding ton ue. arranged to enter said recess for inter ocking said members.

3. A lock bolt comprising clampingmembers having a recess, an intermediate member provided with a yielding tongue having a teat arranged to enter said recess 'for interlocking said members.

4. A lock bolt comprising clamping mem bers having a recess, an intermediate member formed with a longitudinal slot therein,

a ,yielding tongue secured tosaid member and movable in said slot, said tongue being provided with a teat arranged to engage said recess for interlocking said members.

5. A lock bolt comprising clamping members havingrecesses, an intermediate member formed with a longitudinal slot therein, a plurality-of yieldin tongues secured to said member and Inova le in said slot, each of said tongues being provided with a teat arranged to engage 'the adjacent recess for interlocking the members.

6. A lock bolt comprising clamping members having recesses and offset heads, a cavity in said heads,'an intermediate member having ahole disposed in register with said cavity when the members are assembled, a yielding tongue secured to said member and provided with a teat arranged to engage the adjacent recess for interlocking the members.

7. A lock bolt.I comprisin clamping members having recesses and o v set heads, a

cavity-in said heads, an intermediate member having a hole disposed in register with said cavity when the members are assembled, yielding tongues secured to said member, each of said tongues being provided with la teat arranged to `engage the adjacent recess for interlocking the members.

In testimony, that l claim the foregoing as my invention, I have signed my name this 9th day of September 1924.
